I'm writing to recommend something awesome to anyone who's recently signed up for cryonics (and to the future self of anyone who's about to do so). Robin Hanson has a longstanding offer that anyone who's newly signed up for cryonics can have an hour's discussion with him on any topic, and I took him up on that last week.
I expected to have a fascinating and wide-ranging discussion on various facets of futurism. My expectations were exceeded. Even if you've been reading Overcoming Bias for a long time, talking with Robin is an order of magnitude more stimulating/persuasive/informative than reading OB or even watching him debate someone else, and I'm now reconsidering my thinking on a number of topics as a result.
So if you've recently signed up, email Robin; and if you're intending to sign up, let this be one more incentive to quit procrastinating!

The LessWrong Wiki article on cryonics is a good place to start if you have a bunch of questions about the topic.
If you want to argue about whether signing up for cryonics is a good idea, two good and relatively recent threads on that subject are under the posts on A survey of anti-cryonics writing and More Cryonics Probability Estimates.
And if you are cryocrastinating (you've decided that you should sign up for cryonics, but you haven't yet), here's a LW thread about taking the first step.
(Kneejerk response: If only we could engineer some kind of intelligence that could analyze the potentially long tail of x-risk, or could prudentially decide how to make trade offs between that and other ways of reducing x-risk, or could prudentially reconsider all the considerations that went into focusing on x-risk in the first place instead of some other focus of moral significance, or...)
Yes, one of the nice features of FAI is that success there helps immensely with all other x-risks. However, it's an open question whether creating FAI is possible before other x-risks become critical.
That is, the kneejerk response has the same template as saying, "if only we could engineer cold fusion, our other energy worries would be moot, so clearly we should devote most of the energy budget to cold fusion research". Some such arguments carry through on expected utility, while others don't; so I actually need to sit down and do my best reckoning.
